 Founded 1995 by Spieß (git, vox), Dworak (bass, vox) and Grassl (dr),

the band soon gained a loyal following with their mix of Deathmetal and

(mostly) Viennese dialect lyrics, achieving a certain cult status. 

Quote Flex Digest (1997): "Drahdiwaberl auf Speed!".  


After numerous shows in Vienna and Austria (e.g. Flex, Rockhaus, Donauinsel, Arena...), with well-known bands, such

 as Sepultura, Obituary, Vader and many more, the own festival series "Zombiezirkus", the demo MC "Tiafe Gschichtn"

(recorded @ Arena/Vienna 1996), the band disbanded after several line-up changes in 2000. 


 A not quite complete playlist of the demo  

is  online, a little taste of it here:
